Bond strength of glass fibre-reinforced posts with composite cement
Journal Title: Prosthodontics - Year 2018, Vol 68, Issue 2
Abstract
Introduction. The most common failure in using glass fibre-reinforced composite posts is cementation of the post, i.e. the lack of junction between cement dentine or post. Aim of the study. To compare the bond strength between different glass fibre-reinforced composite (FRC) posts and selected composite cement. Materials and Methods. The following seven types of fiber reinforced composite posts (n =10): Fiber Post (GC Europe N.V., Leuven, Belgium), Glassix (Harald Nordin SA, Chailly s/ Montreux, Switzerland), Rebilda®Post (VOCO GmbH, Cuxhaven, Germany), FibreKleer Serrated Post (Pentron Clinical, Wallingford, USA), ParaPost®Fiber Lux (Coltene/Whaledent Inc., Cuyahoga Falls, USA), RelyX (3M Espe Dental Products, St.Paul, USA) oraz X-Post (Dentsply Maillefer Instruments, Ballaigues, Switzerland) were evaluated. Posts were cemented into metal sleeves with dual-cure resin cement CoreXFlow (Dentsply). The bond strength test based on the coaxial method was performed on the samples using Instron 4485 machine (Instron Corporation, Norwood, USA). Results. The significantly higher values of bond strength were demonstrated for Fiber Post (GC Europe N.V., Leuven, Belgium) with 29.57±1.44 MPa, and the lowest were shown by Glassix (Harald Nordin SA, Chailly s/Montreux, Switzerland) with 17.21±0.87 MPa. The differences were significant (p<0.001). Conclusions. 1. The significantly higher values of bond strength were demonstrated for Fiber Post (GC Europe N.V., Leuven, Belgium) and the lowest were shown by Glassix (Harald Nordin SA, Chailly s/Montreux, Switzerland). 2. The resin methacrylic posts had a stronger junction with cement than with epoxy resin posts.<br/><br/>
